This is a chart for how much Kingdom XP you get for your Kingdom Levels and Power level, which is used to work out what your new Kingdom Prestige level is.
This is not related to any Crystals you received. This chart of XP is automatically applied to those Kingdoms and your Kingdom is automatically reverted to their new level.
The Crystals you received are a direct conversion of how many Deeds and Writs you had in your inventory.
